LAM P-HANGER.

SPECIFICATION forming part of Letters Patent No. 698,278, dated April22, 1902. Application filed May 13,1901. Serial No. 59,959. dramas.)

To all whom it may concern: 9

Be it known that I, HENRY JOHN HARRI- SON, a citizen of the UnitedStates, and a resident of Juneau, Territory of Alaska, have invented anew and Improved Lamp-Hanger, of which the following is a full,clear,and exact description.

This invention relates to a device for hanging electric lamps so thatthe lamps may be raised or lowered to any height desired. This end Iattain by a certain arrangement of parts involving a roller or drumcarrying a con ductor and actuated in one direction by a spring, so asnormally to wind the conductor on the drum, the drum being actuatedmanually in the contrary direction and being arranged with a dog whichwill hold it in any position desired.

This specification is a specific description of one form of theinvention, while the claims are definitions of the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

in which similar characters of reference indicate corresponding parts inall the views.

Figure 1 is a front elevation of the invention. Fig. 2 is an enlargedside elevation thereof, and Fig. 3 is a section on the line 3 3 of Fig.1.

The device is preferably inclosed in a protective case or cover, (notshown,) through an opening in which the flexible conductor a of the lampa passes loosely, so that the lamp may be raised or lowered at will.bindicates a suitable framing which carries the working parts of thedevice. In thisframing is moun ted a shaft 0, engaged with a spring 0'and having fast thereto a spur-gear 0?. This gear 0 is in mesh with apinion a, fast on a drum 0 f. As best shown in Fig. 2, thedrum fisprovided with two dogs f, and these are arranged to engage with anotched collar f on the shaft g. The conductor a is wound on thedrumfand has its terminals, respectively, in electrical connection withannular conductorbands It on the drum fat the righthand end thereof.(See Fig. 2.) In sliding contact with these bands h are contact-fingers't', which are mounted'on'but insulated vfrom the frame I) through themedium of an insulating-block 13. These contact-fingers 't are connectedby a conductor is with any suitable source of electrical energy.

position the drum f be turned the fingers v1 will be continually incontact with the bands h, and the current will therefore be trans mittedto the lamp a through the conductor ct. Upon drawing down on the lampthe conductor ct is unwound from the drum f, and therotation of .thedrum causes the roller 0 to be rotated contrary to the rotation of thespring a. If one of the dogsf be then allowed to engage with the notchedcollar f of the-shaft g, the drum will be held and the lamp will be keptat the lowered position. By starting the revolution of the drum andcausing the dogs f to be thrown outwardly by centrifugal force thespring a may be permitted to return the drum to its normal position,winding up the conductor a thereon. From this it follows that the lampmay be raised or lowered, as desired, and that the different adjustmentsof the lamp may be obtained simply by drawing upon or slackening up theconductor a, very much in the same manner as the ordinary springcurtain-roller is operated.

Having thus described my invention, I claim as new and desire to secureby Letters Patent A lamp-hanger, comprising a frame having two dependingparts, a shaft mounted to turn in said parts, the shaft extendingbetween them, a spring actuating the shaft, a drum mounted to turn inthe depending parts of the frame below the shaft, gearing connecting thedrum with the shaft, two annular contact-bands fastened to one end ofthe drum concentric with the axis thereof, contact-fingers fastened tothe adjacent depending part of the frame and bearing respectively onsaid annular contact-bands, electrical conductors leading to thecontact-fingers, electrical conductors wound on the drum and havingconnection respectively with the contact-bands, and means working withthe drum to control its movement.

In testimony whereof I- have signed my name to this specification in thepresence of two subscribing witnesses.

HENRY JOHN HARRISON.
